There is abnormal marrow signal within the T5 and T6 vertebral bodies, with adjacent discontinuity of endplates adjacent to the T5/6 intervertebral disc as well as abnormal enhancement. Abnormal enhancement also involves the anterior T5-6 disc and this is contiguous with a peripherally enhancing linear low signal tract which extends outward beyond adjacent T5-6 anterior osteophytes into the prevertebral tissues and then tracks into the right pleural cavity as a larger, centrally non-enhancing collection. This right paravertebral/pleural collection is similar in size to the prior CT. The adjacent lung parenchyma is collapsed and hyperenhancing, favoured to reflect a reactive change. Small focus of altered marrow signal and enhancement within the adjacent right inferolateral aspect of T4, possibly a further focus of infection secondary to subligamentous spread. No other abnormal focus of enhancement. The imaged thoracic cord maintains normal signal and contour. Partially imaged renal cysts.
